CVE-2026-81694 PUBLISHED

verify-usb before 1.4.9 Output Injection via Unsanitized Filenames

Assigner: VulnCheck
Reserved: 27.08.2026 Published: 27.08.2026 Updated: 27.08.2026

openssl-encrypt (pip package, versions <= 1.4.8) fails to sanitize filenames read from untrusted drive data (outside the AES-GCM authenticated manifest) before printing them in the verify-usb command's output. An attacker can plant filenames containing terminal cursor-movement and erase-line control bytes that repaint a forged PASSED verdict on screen, masking actual tamper detection. Fixed in 1.4.9 by routing drive-derived names through sanitize_for_display().
